STEINS;GATE RE:BOOT Moeka Ending & Gamma Worldline
Unlock the STEINS;GATE RE:BOOT Moeka ending on the Gamma worldline, see what is newly written, and compare it with Hyde of the Dark Dimension.
The Moeka ending in STEINS;GATE RE:BOOT is the Chapter 9 branch: save at the D-Mail prompt and do not send. That is the only unlock. Everything below is labeled so you can stop before story.
How to unlock (spoiler-free)
- Reach Chapter 9 on the “keep going” worldline (you already sent/called through Chapters 6–8).
- Save.
- Decline the D-Mail.
- Trophy: Hide in Darkness.
Reload and send the D-Mail to continue toward Chapter 10. Optional: ignore a late Chapter 9 Kurisu call for a Moeka extra scene on the main line — that scene is not the ending.
What’s new (light spoilers)
Original STEINS;GATE and ELITE never gave Moeka a dedicated heroine route. RE:BOOT does. Kiri Kiri Basara’s review team says the route is mostly new writing, only loosely based on Drama CD Hyde of the Dark Dimension (Gamma). Noisy Pixel also flagged the route as short — that is a reviewer opinion, not a fact about missing trophies.
Official Spike Chunsoft copy: Okabe is thrown onto a worldline where the time machine was never completed and D-Mails do not exist, and Hououin Kyouma never existed as the lab’s driving persona.
Gamma worldline explained (heavy spoilers)
Skip this heading if you only wanted the button prompt.
On this worldline Okabe does not have the lab as he knows it. The route exists to give Moeka the same “heroine ending” slot the other lab members already had, and to add a Gamma-flavored what-if rather than replay the Drama CD beat-for-beat. KKB notes extra Moeka voice work from Saori Goto because she simply has more scenes.
